I think he died.
This was already suggested...
Can someone who has bought from him before Contact him? You have his address? Do you have a Phone # anyone? We should try and contact him, someone has to have more of his info, can that person please try and contact him?
This would really help out.
EDIT: Do not post his info just please try and contact him.
Yes, I know. But even more so now, so I found the need to restate it.
